To dit whom it wwg/fconcem: Y

Bie it known that I, Vieron H. SLiNAeIr, a citizen of the United States,residing at the cityotx Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented a certainl new yand useful Ingverted Encalndescent vGras-Burner, of which thel following is aspeciication.

The principal obj ect of the present invention is to provide for keepingall the mantlesfor incandescente of the group of niantles orineandescents of a burner equally bright, or in other words to keep allthe inantles of the burner ofv uniformy brightness.

Another object of the invention is to prof vide a comparativelyinexpensive, reliable' and simple inverted incandescent gas burner ofhigh candle power. l

Other objects of the invention will appear from the followingdescription.

The invention will be claimed at the end hereof, but will be firstdescribed in connection with the embodiment of it chosen forillustration in the accompanyingl drawings, in whichf Figure 1, is aside view partly in section. Fig.V 2, is a sectional plan view von theline 2 2 of Fig. l. Fig. 3, is a sectional view on the line 3-3 of Fig.l, looking upward.

In the drawings the incandescent gas burners 1 having burner tubes 2constitute a group of, as sho-wn in the drawings, five burners, but thenumber may beincreased o-r diminished. It will usually be three or more,but the number is not to be regarded as essential. y

3, is a tubular gassupply ring shown as arranged concentric with thegroup of incandescent gas burners.

4, is a tubular gas supply yoke from the arms 5 of which the ring 8 issuspended.

6, are inverted U-shaped. Bunsen tubes each provided with a gascontroller 7 and rising from the ring 3. These Bunsen tubes make up agroup containing, as shown in the drawings, three Bunsen tubes spacedaround the ring 3, although the number of Bunsen tubes may be increasedor diminished.

8, is a mixing and supply chamber com-` of the chamber 8 and the burnertilbsy are s lioavn to lead radially or tliereabou-t from the base ofthe mixing chamber.

l0, is an'leeltlen ses? noodles tube yby-passes.v the Bunsen-tubes andeonirnuni-v icates with the burner tubesrby way of the 'chamber 8. n

`11, is an inner shell wall. of the mixing chamber 2?;` and inolosi-ngthe descending parts of the Bunsen tubes. 12," is V`an outer shellexcluding the rising.

mounted on the side parts of the Bunsen tubes and the arms 5T;

of the` yoke. As shownthe plate 13a incloses the .bottom of the mixingehaniber and con-Y stitutes in. effe@ a part Ot the inner Slee/11:,`,and is supported by a screwl?) connected `with the base of thechainber8V, and the outer shell is supported by screws la ,thatv are connectedwith the ends- .of they arnisr;

'y of the yoke. is e. deeetor which, if desir-@6Ll may# also, beret-lector audit extends-entrarn M flem ,the base of the .OuterShell.:`Y The products ofcombustion pass up be.

tween die outer and inner shells' and there fore are not taken in at theair inlets 16 'of .tlie Bumsen tubes. y These shells protect the supplyconnections of the burner from undue exposure to the heat of theproduets of combustion. ln the chamberv 8 a thorough stirring up of themixture of gas andair is effected and the surface 9 promotes suchthorough stirring up as does also vthe de. scribed arrangement vot'theinl'et andoutlet ture to each of the burners so that they are burneris lighted, thus avoiding explosions y at that time and `it is-Wellunderstood that st-antially as described.

9.. An inverted incandescent gas burner comprising'the combination of agroup of incandescent gas burners having burner tubes, a gas supplyring, a. gas supply yoke from the arms of which the ring is suspended, agroup of inverted U-shaped Bunsen tubes rising from the ring, a mixingand supplyichamber common to all the Bunsen tubes and to all the burnertubes, and an ignition gas flooding tube by-passing t-he Bunsen tubesand communicating Wit-h the mixing and supply chamber, substantially asdescribed.

3. An inverted incandescent gas burner comprising the combination of agroup of incandescent gas burners having burner tubes, a gas supplyring, a gas supply yoke from the arms of which the ring is suspended, agroup of inverted U-shaped Bunsen tubes Vrising from the ring, a mixingand supply chamber common to all the Bunsen tubes and to all the burnertubes,fan inner shell inclosing the bottom and side Walls of the mixingchamber and the descending parts of the Bunsen tubes, and an outer shellexcluding the rising parts of the Bunsen tubes and the arms of the yoke,substantially as described.

i- An inverted incandescent gas burner comprising the combination of agroup of incandescent gas burners having .burner tubes, a gassupplyring, a gas supply yoke from the arms of which the ring is suspended, agroup of inverted U-shaped Bunsen tubes rising from the ring, a mixingand supply chamber common to all the Bunsen tubes and to all the burnertubes, an inner shell inclosing the bottom and side Walls of the mixingchamber and the descending parts of the Bunsen tubes, an outer shellexcluding the rising parts of the Buns'en tubes and the arms of theyoke, and a delector extending outwardly from the base of the outershell, substantially as described.

5. An inverted incandescent gas burner comprising the combination of agas supply yoke, a gas supply ring carried by the arms of the-yoke,invertedv U-shaped Bunsen tubes rising from the ring and dependinginward toward the center thereof, a mixing and supply chamber dependingfrom the descending ends of the Bunsen tubes, and burner tubescommunicating with the base of the chamber and carried thereby,substantially as described.

In testimony whereof` I have hereunto signed my name.
